Archaeologists have discovered hundreds of ancient Aboriginal artefacts off the coast of Western Australia.

The finds were made off the Pilbara coast in the Dampier Archipelago of Western Australia and include stone tools and grinding stones. The artefacts have remained undisturbed for thousands of years since they were first deposited on dry land and later inundated by sea level rise.

One site at Cape Bruguieres with 269 stone tools is 2.4 metres below modern sea levels and dates back at least 7,000 years. The second site in Flying Foam Passage is an underwater freshwater spring at 14 metres below current sea levels and dates back at least 8,500 years.
